APPARATUS FOR TREATING YARN.

SPECIFICATION forming part of Letters Patent No. 622,001, dated March28, 1899.

Application filed April 26,1898. Serial No. 678,828. (NomodeL) To all10720171 it may concern: 7

Be it known that I, JOHN GREGSON, of Fall River, in the county ofBristol and State of Massachusetts, have invented a new and usefulImprovement in Apparatus for Treating Yarn; and I hereby declare thatthe following is a full, clear, and exact description of the same,reference being had to the accompanying drawings, forming part of thisspecification.

This invention has reference to an organized apparatus for treating yarnon the cop or bobbin for use in the'loom.

The object of the invention is to prepare filling-yarn,and particularlyfilling-yarn spun on ringspinning frames, for use in the shuttles of thelooms expeditiously and without injuring the bobbins; and to this endthe invention consists in a'suitable receptacle in which thefilling-yarn is placed while on the bobbin or cop and mechanism by whichair charged with water is drawn through the filling, whereby the twistin the yarn is set and kinks in the yarn avoided.

Filling-yarn spun on ring-spinning machines is wound on bobbins usuallymade of wood and varnished. The yarn in the process of spinning istwisted and laid spirally on the bobbins. ofi the bobbins, any slacknessin the same will cause it to kink. Mule yarn being spun either on thebare spindle or on paper quills is usually steamed, which causes thetwist to set; but bobbins when subjected to steam are liable to alter inshape and the varnish on the same soften, so that-the yarn will stick tothe bobbins, and as filling-bob bins are built up in conical layers'oneor two rings of each conical layer in contact with the varnish on thebobbin-they will become cemented to the bobbin and the yarn on the sameis liable to break at each conical layer, making such bobbins unfit foruse in the shuttle on account of the frequent breaks in the filling.

In my apparatus a forced current of air is made to pass through spraysof finely-divided streams of water, forming a mist, in which therapidly-moving air carries the atomized water onto, around, and betweenthe filling- When the yarn is now drawn yarn on the bobbins, by whichthe Water mechanically carried by the air is absorbed and the air isdrawn from the upper part of the receptacle to be forced again throughthe sprays of water and through the mass of bobbins containing thefilling-yarn. By the use of this apparatus the filling-yarn can bethoroughly moistened in a very short time'without injuring the bobbinsor affecting the varnish on the same. tinuously added and the moistenedbobbins withdrawn, or the apparatus may be used to dampen the filling ona batch of bobbins and then by stopping the fioW of the water partly drythe bobbins by forcing the air under normal conditions through thechamber containing the bobbins.

Figure 1 is a front view, partly in section, of my apparatus. Fig. 2 isa vertical longitudinal section of the same.

In the drawings I have shown the apparatus in connection with the floorsabove and below the chamber into which the bobbins are placed, thisbeing the construction I have used and which illustrates the bestpractical application I have so far made of the invention. I donot,however,wish to confine myself to the exact relation of theapparatus to the floors or to the exact relation of the Various parts toeach other, as they may be altered and arranged to best adapt theapparatus to the existing conditions and the convenience of the user. V

In the drawings, A indicates the floor on which the apparatus issupported; 13, the upper floor; O, a chamber, the four sides, the

top, and the bottom of which may be made of seasoned Wood or othermaterial, (the chamber should be practically air-tight;) D a trunkextending from the chamber 0 upward above the floor B and provided withthe cover d, preferably hinged at one side to the trunk; E, an inclinedgrating, and F the doors, preferably arranged to slide on vertical waysand New bobbins may be con-.

connected with the counterbalance-weightf 5 by a chain or cord passingover a pulley. The chamber 0 is preferably provided with the inclineddeflector c. The bobbins containing the filling-yarn are thrown into thechamber 0 through the trunk D and are supported on ISO the grating E,which is sufficiently inclined to cause the filled bobbins to slide androll on the grating toward the doors F.

In practice the chamber is filled with the filling-bobbins at or nearlyto the point where the dcfiectorc projects from the vertical wallforming the front of the chamber.

The pipe G is a pipe connected with a watersupply under pressure. It isprovided with a valve G, by which the water-supply is controlled. Thelower end of the pipe G connects with a pipe extending across thechamber under the higher end of the grating E. From this transverse pipea series of pipes G2 extend longitudinally and are each provided with aseries of atomizers G G consisting, as shown in Fig. 2, of a nozzle anda deflector supported in front of the nozzle, by I which the waterejected underpressure from the nozzle is broken up and distributed,forming a mass of spray under the grating E. The lower part of thechamber is lined with tin or other waterproof material and is providedwith the drain-pipe G, by which the surplus water is carried oif. Thewater-atomizing apparatus just described is one of several well-knownmeans for subdividing the water into aspray, and any other well-knowndevice adapted to form a continuous spray under the grating or supplythe air in the part of the chamber under the grating E with water spraymay be used in lieu of the apparatus described.

The pipe H, connected with the upper part of the chamber 0, extendsdownward and connects with the blower II and from the blower with thelower part of the chamber C below the grating E. The blower H may be afanblower or a pressure-blower. Then a @011- siderable depth offilling-bobbins is to be treated at one time, a pressure-blower ispreferred. The blower is driven by a belt connecting the pulley on theblower with the driving-pulley H which is driven from some convenientshaft or prime motor.

\Vhen it is desired to complete the treatment of the filling in theapparatus by circu= lating air through the mass of filling-bobbins afterthey have been thoroughly dampened or it is desired to increase thecapacity of the air to carry the water sprayed into the lower part ofthe chamber through the mass of filling-bobbins, the chamber 72,,provided with a coil of steam-pipes, as indicated in- Fig. 1, may beplaced at any convenient part of the pipe II, so that the air in passingthrough the chamber 7?, may be slightly heated and the capacity of theair to absorb and to carry moisture increased.

The operation of the apparatus is as follows: hen the chamber 0 has beenpartly filled with filling-bobbins to a point above the openings for thedoors F and preferably to a point above the lower edge of the deflectorc, the water may be let onto the spraying devices and the blower I'l'started. As the blower draws the air from the upper part of the chamber0 a partial vacuum is produced in the part of the chamber above the massof filling-bobbins, and as the blower forces the air into the lower partof the chamber 0 below the gratin g E a plenum exists in this part ofthe chamber, and the air, passing through the sprayed water, carries thewater through the grating onto, between and through the mass offilling-bobbins, depositing the moisture of the filling-yarn. The lowerportion of the mass of bobbins is the first to be thoroughly dampened.By opening the doors F F the lower bobbins may be removed from thechamber from time to time and more filling-bobbins added to maintain aconsiderable depth of bobbins.

The deflector portion 0 facilitates the withdrawing of the lower portionof the mass of bobbins, as it prevents the descent of the upper mass ofbobbins at the front near the doors.

All the filling on the bobbins in the chamber may be suificientlydampened in a short time by running the blower at a high speed, so as toproduce a rapid circulation of the air and a partial lifting of thebobbins by the greater air-pressure below than above the bobbin mass,and after operating the spraying devices fora suificient time and thenshutting off the water-supply the rapid upward circulation of the airwill carry any excess of moisture from the lower bobbins and distributethe same equally through the mass of bobbins. A slight heating of theair in its passage through the chamber h will facilitate the process;but the air must not be heated so as to affect the bobbins or thevarnish on the same.

Filling-yarn treated as above described has the twists perfectly set anddoes not kinkwhen slack, as I does the untreated filling. It istherefore better adapted for use in the loomshuttle.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In an-apparatus of the nature herein described fortreating filling, the combination of the following instrumentalities: achamber having an inlet-opening and the top, an inclined grid, orgrating, for the support of the filling, a water-spraying device underthe grid, or grating, a blower connected with the upper and the lowerpart of the chamber, and a door for the discharge of the filling;whereby the filling may be dampened, as described.
